LEOPOLD BENNETT, OF PITTSBURG, PENNSYLVANIA.

STEAM-VALVE.

Specification of Letters Patent No. 28,552, dated June 5, 1860.

To all whom t may concern:

Be it known that I, LEOPOLD BENNETT, of Pittsburg, in the county of Allegheny, in the State of Pennsylvania, have invented a new and Improved Mode of Steam-Engine Balance-Valve; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in admitting the steam directly through the valve, thus obviating the necessity of its being forced into contact with the working surfaces, and thereby avoiding friction.

MyI object is to relieve the steam valve as far as possible from unnecessary friction.

Passage marked A in Nos. l, 3, 4, and 5, indicates the steam passage through the valve; and the direction of the entering steam is indicated by the arrows. Arrow B shows the steam entering the valve from the steam pipe, or throttle valve. Arrow C shows the steam entering the pasage of the cylinder at one end, while d shows it escaping from the other end; and e shows its exit through the valve. The

direction of the exhausting steam is also shown at @Z in the section of the valve No. 5, and at e in Nos. l and 5.

No. l is an end view of a section of the valve chamber, showing the steam passages, with an end view of 'the valve in its place. No. 2, is an end view of the valve; No. 3, a section of the valve through the apertures. F and F are the exhaust apertures. No. 4L is an upright longitudinal section of The valve can Ine worked by any ordinary plan of the valve; and No. 6, is an end view of the valve chamber.

The valve can be worked by any ordinary eccentric or cam, or any of the usual appliances for working slide or puppet valves.

I claim as my invention, and desire to secure by Letters Patent- The construction of a valve oscillating or Working in the same manner as a cock, with the steam passage transversely through it, and the exhaust through it in the direction of its length, as in the manner hereinbefore described by reference and drawings.
